The aim is to study the kinetics of the oxidation of 5-hydroxymethylfurfural catalysed nitroxyl radicals and the regioselectivity of the oxidation . The catalytic activity of various systems has been investigated by measuring amount of the absorbed oxygen . The reaction products were studied by NMR spectroscopy. It was shown that the main product of the oxidation in the presense of N- hydroxyphthalimide / Cu(NO3)2*3Н2O is 2,5-diformylfuran . In contrast to known methods of oxidation reaction proceeds with high yield and selectivity under mild conditions. Oxidation product - 2.5 diformylfuran - is the promising monomer, and also it finds application as a base for the synthesis of new drug formulations, Product Description popup.authors Літвінов Юрій Євгенович popup.nrat_date 2020-04-02 Close
